Do programs to monitor disk usage exist?

Thrifty · 02-04-2004, 02:56 PM

I guess the title says it all. Does there exist software that can monitor disk usage across the varied partitions of a computer and notify you if disk space usage has reached a certain threshold? Say, could it be set up so that if 90% of the space was used up on a hard drive, that a message informing me of that could be automatically E-Mailed to me?

check out partmon. i have no clue how to use it or anything, but it sounds like what you might be looking for:

Is that distribution specific? I use SuSE, and I didn't find anything like that available, nor did I find it available on the installation disc.

actually it does look like it is specific to Mandrake; my Slackware box didn't have it. df will tell you how much free space you have--maybe you can set it up to automatically run or something. i wish i could help you more but i'm still learning myself.

No good. The du command will tell me how much of the drive is being used, but I have to do it manually. I'm looking for something to do automatic alerts and such.

But it's a moot point now. I've found something that should do this for me. Thanks for your help folks.

just out of curiosity, what did you find?

Well, it's a script my boss wrote. I'd show it to you, but it's not really my code to share, and he might not be comfortable with me putting that information out there. I don't know what kind of potentially sensitive information a saavy computer whiz reading this board could pluck out of it. I'm probably being paranoid, but I prefer to think of it as "better safe than sorry".

No. The "Open Source spirit" is currently hiding under the "Don't Get Chewed Out by the Boss" spirit.

Quick and dirty. Modify to fit your needs

Code:

for fs in `df|tail +2|awk '{print $6}'`
do
let percentUsed=`df $fs|tail +2|awk '{print $5}'|cut -f1 -d'%'`
if [ $percentUsed -gt 89 ]
then
  echo $fs is getting full -- it\\'s $percentUsed used
fi
done

That will grab file system that is over 89 percent full and simply tell you it is getting full. You could add additional conditions to it pretty easily. You could pretty easily have this generate an email to send out to alert you.

Stick this in a script and have it run in a cron job every hour, or sooner if you like.

Hmmm. Might have to add this to my profile...

Also, another option is to head out to sourceforge and look for LRRD or Munin. It's a little bit of work to install but it tracks a butt load of things about your server. Disk usage, disk space, network traffic, swapping, apache processes, and a bunch of others. Optionally you can have it throw alerts to nagios.
